Description
Baichen Li, Giuseppe Marrazzo, Marta Poyo Solanas, and Beatrice de Gelder trace how information about whole-body actions flows through the brain region that reads bodies. The lateral occipitotemporal cortex handles objects, bodies, and expressions, but how its subdivisions pass action information around was unclear. Their 2025 study records brain activity as people view different whole-body actions, and models the direction of flow between the region's parts. Different actions drive distinct flow patterns, suggesting the subdivisions divide the labor of reading a moving body.
Knowing who does what, from a glance, is a social survival skill, and this cortex is its hub. A flow map upgrades the picture from areas that light up to a circuit that computes. The authors use time-sensitive methods to get direction, not just activity. Their findings refine models of action perception. The work sits in cognitive neuroscience, with body language as the test case.
